To all whom it may concern:

Be it known that 1, JAMES L. WELLS, a citizen of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented certain new and useful Improvements in Apparatus for Utilizing Hot Slag for Heating Purposes, of which the following is a specification.

This invention relates to apparatus for utilizing hot slag for heating purposes, its object being to so construct a receptacle that the molten slag may be applied to and held in contact with the exterior surface of the receptacle and be easily discharged therefrom when necessary.

In the accompanying drawings I have illustrated my invention as applied to a steamgenerator and to a hot-blast apparatus; but i it is evident that it may be applied to receptacles for other purposes, and hence I do not limit the invention to such uses.

In the accompanying drawings, Figure 1 is a side elevation of a steam-generator embodying my invention, some parts being omitted to more clearly show the construction of other parts. Fig. 2 is a transverse section on the line 2 2 of Fig. 1. Fig. 3 is a similar section on the line 3 3 of Fig. 1. Fig. lis a side elevation of a hot-blast apparatus embodying my invention; Fig. 5, a transverse section on the line 5 5 of Fig. 4, and Fig. 6 a horizontal section of a portion of Fig. 4. Fig. 7 is a sectional detail of the sliding rod and its guide, shown in Figs. 3 and 5.

In carrying out my invent-ion I provide a series of chambers on the exterior of the receptacle and partially surrounding it,one side of each chamber being movable for the purpose of discharging the slag and each chamber having a filling-aperture. These chamhers may be formed in many ways and be of any desired shape, provided they be entirely on the exterior of the receptacle, and while the construction illustrated in the drawings and to be now described is preferred it must be understood that my invention is not limited to such construction.

Referring to Figs. 1, 2, and 3, it will be seen that the generator consists of a cylindrical portion or shell A, having the usual steamdome a and a series of ribs or projections 13.

These ribs or projections are hollow and extend nearly around the shell A, and each is connected at its lower portion to a blow-off pipe 0 by means of a pipe I). They may be secured to the shell in any desired manner and will be in communication with the interior of the shell through openings 10 and 11, so that the water in the generator will circulate freely through them and the shell.

The ribs or projections B are spaced apart, preferably, uniformly and vertical fillingplates D are inserted in the spaces between them at their lower portions. These plates may be secured to the ribs in any approved manner and form a tight joint at their upper ends with the shell A and at their vertical edges with the opposing sides of adjacent ribs. Preferably tWo plates will be used, one on each side of the pipe 0, and these plates form the bottoms of the slag-receiving chambers, while opposing faces of adjacent ribs and that part of the shell A included between them will form three of the sides of such chambers. The other or front side must be movable, and, as shown, it consists of a curved plate E,hinged at its upper end to the ribs and so shaped that when closed its lower end will abut against the plate D and its inner face fit closely against the outer face of the ribs. Preferably there will be a separate front plate E for each chamber; but it is obvious that one plate may be used to close the fronts of all the chambers, or a series of plates may be employed each adapted to close the fronts of two or more of the chambers. Also, preferably, there will be a projecting portionf on the plate to fit in between the opposing faces of adjacent ribs.

Some means must be provided to hold the plate or plates E in closed position and also to open it or them, and one convenient way is to provide a fixed vertical guide-rod F for each plate, adjacent thereto,on which a pullrod G is supported to slide vertically. The lower end of this rod is connected to a head or block 20, which is mounted to slide upon I For convenience in introducing the slag into the chambers a platform or floor may be constructed above the generator,as indicated by H, and a series of funnels I be supported in such floor or platform, one for each chain- 1 The upper ends of the chambers may be partially closed or be left entirely open, as

preferred.

It will thus be seen that I provide a series of heating-chambers on opposite sides of the generator and that three sides of each chamher are in direct contact with the water to be heated, thus affording a large area of heatj ing-surface for the generator.

the funnels sufficient to fill the chambers to a point just below the waterline of the boiler, and all or only a portion of such chambers may be so filled. After the slag has solidified and parted with most of its heat the plate E i of each chamber will be swung open by eleof the chamber.

the slag contracts as it cools.

Referring now to Figs. 4, 5, and 6, K represents a hot-blast box, semicylindrical inj form and closed at both ends, except as to The box the inlet and outlet pipes and 70. is also closed at its upper flat side, preferably by a removable cover X, and its circular portion is formed with a series of corrugations 1 or ribs B, which are similar in shape to the ribs or projections B, already referred to, exj cept that there is no partition between their interiors and the main chamber of the box. I In this apparatus the box may be conveniently cast, so that the ribs or corrugations will be an integral part thereof.

Front plates E are hinged at their upper ends at e and when closed are adapted to engage the plate D with their lower ends and the front faces of They are also 1 provided with raised portions f to fit in between opposing faces of adjacent ribs.

the slag is poured into t'hechambers. In order to compel the air to contact with the heated surfaces of the corrugations, I provide a series of baffle-plates or deflectors M, which may be suspended from the cover X and project into the corrugations B, thus compelling the air to follow a tortuous passage in contact with the interior faces of the ribs B. The operation of this apparatus will, so far as the use of the slag is concerned, be precisely like that of the steam-generator heretofore described, only it will heat air instead of water. I

If preferred, each of the plates E or E may be provided with a projection O at its upper end, extending inwardly in such position that when the plate is swung open such projec tion will contact with the upper end of the solidified slag and force the latter out of the chamber in the event it should tend to stick to the walls of the chamber.

Having thus described my invention, I claim- 1.
